Pointwise estimates and Liouville theorems for positive supersolutions of (p, q)-Laplace equations

We study positive supersolutions of quasilinear elliptic problems driven by the (p, q)-Laplace operator which arise in models with nonstandard and unbalanced growth. Our approach is based on an explicit construction of radial solutions and torsion functions that serve as comparison functions. This gives a fundamental p...
